Welcome / Bienvenidos

The sustainable viticulture practices that Caliterra has been using in the vineyards are:

Plant Health

Caliterra works with the IPM (Integrated Pest Management), a combination of biological, chemical and cultural practices to minimize environmental impact.

• Environment friendly phytosanitary programs based on low health and environmental impact products.
• Favoring biological control for pests and the use of low impact products on natural enemies.
• Use of advanced monitoring systems that allow the segregation of control areas.
• Product rotation to prevent resistance.
• Adequate light and ventilation in canopy management to minimize diseases.
• Minimal use of herbicides.

Irrigation Water Management

The rational use of water resources in the Caliterra vineyards is essential to achieve a sustainable wine production. The development and improvement of our irrigation strategies, aimed at maximizing the efficiency in water use and maximizing the quality of our products, has been done with the following procedures:

• Controlled irrigation that allows minimal use of water resources.
• Use of technology and instruments (Scholander Camera) to measure the plant’s real water status.
• Use of un-contaminated water sources.
• Reducing the unnecessary use of energy.
• Nutrition and Fertilization

Caliterra’s policy is to use fertilization in a minimal, rational manner. This implies the following activities:

• Implementation of fertilization plans based on nutritional balance, analysing foliar nutrients and soil. The objective is to know what, when and how much is needed as an input so we do not generate any fertilization excess.
• Avoid the use of nitrogen-based products that can contaminate the groundwater. If required, they are provided organically.
• Use of organic matter to enrich the soil’s microflora and improve its fertility.

Precision Agriculture

Top of the line technology has been introduced to develop a strong precision agriculture that allows an intensive and detailed management of every specific location in the vineyard, while maximizing quality and productivity with a rational use of resources. In this sense, Caliterra has introduced the use of:

• Multispectral aerial photography for mapping the vigor and water-use.
• Software for interpreting vigor maps and samplings; monitoring of plagues and diseases. This permits specific managements of vegetal sanity, irrigation and harvest.
• Scholander Camera: plant water measurement.
• Foliar nutrient analysis.
• Soil chemical and physical analysis.
• Use of automatic weather stations.
• Use of soil thermometers.
